Relative Percentage Index (RPI)

Relative Percentage Index (RPI) is widely used to produce power ratings. Unlike most power rating systems, the RPI does not consider margin of victory or how well a team has played. It only considers whether a team won or lost. In fact, the RPI is based entirely on winning percentage. It essentially measures a team’s strength of schedule and how a team does against that schedule. It is based 25% on a team’s winning percentage, 50% on the winning percentage of their opponents, and 25% on the winning percentage of their opponent’s opponents.
